'IMPROVEMENT-1N TInEsnniNKINe-MAcsINns.

TO ALL WHGM -IT MAY CONCERN.:

vBe it known that I, JAMES ELLIOTT, of Milford, in the countyJel'erson,and'State of Wisconsin, have invented a new and improved Tire-ShrinkingMachine; and I do hereby declaro that the following is a full, clear,and exact description thereof, which will enable others' skilled in theart tomake and use the same, reference being had to the accompanyingdrawings, forming part of this specification,

This invention relates to adevice for tire-shrinkingand consists of aplatform and bed-piece, the rlatter supportngvtwo slidingcarriagescarrying a `notched or. toothed flange, against which the tire lto beshrunk is set, and held ineplace by two notched'or ratchet-cam levers,vmounted on`the same carriages, which are pressed together bygone or twoother cam-levers, hung on vertical axes on the bed-piece, thus shrinkingthe tire. In thev accompanying drawings- Figure is a topview. of myimproved tire-shrinker, and

Figure 2 a front view'thereowith part of the platform removed to exhibitthe manner in' which one of the' movable carriages runs.

Similar' letters' of reference indicate corresponding parts.

A A is the platform;` B, the bed-piece; C, the ange, toothed or notchedon the side against -which the tire 'I to be shrunk isplacefl; D D, twocam-levers, having toothed heads corresponding with the flange C. Theflange C and levers D are borne on the sliding carriages E, which aredrawn open by the rod or strap and 4chain G,

attached to the levers F,or maybe separatedby-a spring, and are pressedtogether bythe cams F, hung on the vertical axesf. The carriages slideon the runners or T-sli'aped lugs e, in a slot, Z, in tl1ebed-piece`]3,and l groove a in `the platform Arthe slot 6 and groove a formingtogether a T-shaped groove to receive -the runner or T-shaped lug e. Y

The tire to he shrunk is heated, the carrianfes o cned, the tire lacedaffainst 'the flan D'e C, and ammedb the cam-levers D, which for thatpurpose areforced into the position shown inthe drawings. The carriagesare 4 then pressed together by forcing open the cam-levers F. For lightwork, one of the carriages may be made stationary byleavingone of thevcam-levers Fopen, sliding only one carriage o'pen before inserting the`heated tire, the open carriagebeing then pressed towards the stationaryone bythe camfleverF connected with it'.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is'- v1. The combination, ofthe connecting-rodor chain 'G for opening the carriages, with the carriage E andcam-levers substantially as described.

2. The slot b in the bed-piece B, and the vgroove a in the platform A,making together a Tfshaped groove, in combination with a T-shaped lngupon the carriages, alll as substantially specified and described.
